Measles is an acute viral infectious disease. References to measles can be found from as early as the 7th century. The disease was described by the Persian physician Rhazes in the 1. In 1. 84. 6, Peter Panum described the incubation period of measles and lifelong immunity after recovery from the disease. Enders and Peebles isolated the virus in human and monkey kidney tissue culture in 1. The first live attenuated vaccine was licensed for use in the United States in 1.

WHO fact sheet on measles providing key fact, signs and symptoms, who is at risk, treatment, prevention, WHO response. The diagnosis of dengue is usually made clinically. The classic picture is high fever with no localising source of infection, a petechial rash with thrombocytopenia.

The measles virus is a paramyxovirus, genus Morbillivirus. Fibrous Cortical Defect In Adults. It is 1. 20–2. 50 nm in diameter, with a core of single- stranded RNA, and is closely related to the rinderpest and canine distemper viruses. Two membrane envelope proteins are important in pathogenesis. They are the F (fusion) protein, which is responsible for fusion of virus and host cell membranes, viral penetration, and hemolysis, and the H (hemagglutinin) protein, which is responsible for adsorption of virus to cells. There is only one antigenic type of measles virus. Although studies have documented changes in the H glycoprotein, these changes do not appear to be epidemiologically important (i.

Measles is a systemic infection. New York Summer Courses For Adults. The primary site of infection is the respiratory epithelium of the nasopharynx. Two to three days after invasion and replication in the respiratory epithelium and regional lymph nodes, a primary viremia occurs with subsequent infection of the reticuloendothelial system. Following further viral replication in regional and distal reticuloendothelial sites, a second viremia occurs 5–7 days after initial infection. During this viremia, there may be infection of the respiratory tract and other organs. Measles virus is shed from the nasopharynx beginning with the prodrome until 3–4 days after rash onset.

Koplik spots (rash on mucous membranes)Rash. The incubation period of measles, from exposure to prodrome, averages 1. From exposure to rash onset averages 1. The prodrome lasts 2–4 days (range 1–7 days).

It is characterized by fever, which increases in stepwise fashion, often peaking as high as 1. F –1. 05°F. This is followed by the onset of cough, coryza (runny nose), or conjunctivitis. Koplik spots, a rash present on mucous membranes, is considered to be pathognomonic for measles. It occurs 1–2 days before the rash to 1–2 days after the rash, and appears as punctate blue- white spots on the bright red background of the buccal mucosa. The measles rash is a maculopapular eruption that usually lasts 5–6 days. It begins at the hairline, then involves the face and upper neck.

During the next 3 days, the rash gradually proceeds downward and outward, reaching the hands and feet. The maculopapular lesions are generally discrete, but may become confluent, particularly on the upper body. Initially, lesions blanch with fingertip pressure. By 3–4 days, most do not blanch with pressure. Fine desquamation occurs over more severely involved areas. The rash fades in the same order that it appears, from head to extremities.

Other symptoms of measles include anorexia; diarrhea, especially in infants; and generalized lymphadenopathy. Top of Page. Complications. Measles Complications by Age Group. Measles Complications. Diarrhea. 8%Otitis media. Pneumonia. 6%Encephalitis.

WHO World Health Organization. Our focus is to monitor and assess the impact of strategies and activities for reducing morbidity and mortality of vaccine- preventable diseases. Collection, analysis and interpretation of surveillance data is vital to guide vaccination policies and programmes and ensure immunization targets are being reached.

Our core activities consist of the disease surveillance and burden, monitoring of immunization systems and reporting of data and statistics and are guided by the principles set out in the (Global Vaccine Action Plan).

Diphtheria: Causes, Symptoms, and Diagnosis What is diphtheria? Diphtheria is a serious bacterial infection that affects the mucous membranes of the throat and nose. Although it spreads easily from one person to another, diphtheria can be prevented through the use of vaccines.

Call your doctor right away if you believe you have diphtheria. If it’s left untreated, it can cause severe damage to your kidneys, nervous system, and heart. It’s fatal in about 3 percent of cases, according to the Mayo Clinic. What. causes diphtheria? A type of bacteria called Corynebacterium diphtheriae causes diphtheria. The condition is typically spread through person- to- person contact or through contact with objects that have the bacteria on them, such as a cup or used tissue.

You may also get diphtheria if you’re around an infected person when they sneeze, cough, or blow their nose. Even if an infected person doesn’t show any signs or symptoms of diphtheria, they’re still able to transmit the bacterial infection for up to six weeks after the initial infection. The bacteria most commonly infect your nose and throat. Once you’re infected, the bacteria release dangerous substances called toxins. The toxins spread through your bloodstream and often cause a thick, gray coating to form in these areas of the body: In some cases, these toxins can also damage other organs, including the heart, brain, and kidneys. This can lead to potentially life- threatening complications, such as: What.

Children in the United States and Europe are routinely vaccinated against diphtheria, so the condition is rare in these places. However, diphtheria is still fairly common in developing countries where immunization rates are low. In these countries, children under age 5 and people over age 6. People are also at an increased risk of contracting diphtheria if they: aren’t up to date on their vaccinationsvisit a country that doesn’t provide immunizationshave an immune system disorder, such as AIDSlive in unsanitary or crowded conditions What. Signs of diphtheria often appear within two to five days of the infection occurring. Some people don’t experience any symptoms, while others have mild symptoms that are similar to those of the common cold.

The most visible and common symptom of diphtheria is a thick, gray coating on the throat and tonsils. Other common symptoms include: Additional symptoms may occur as the infection progresses, including: If you have poor hygiene or live in a tropical area, you may also develop cutaneous diphtheria, or diphtheria of the skin. Diphtheria of the skin usually causes ulcers and redness in the affected area. How. is diphtheria diagnosed? Your doctor will likely perform a physical exam to check for swollen lymph nodes. They’ll also ask you about your medical history and the symptoms you’ve been having. Your doctor may believe that you have diphtheria if they see a gray coating on your throat or tonsils.

If your doctor needs to confirm the diagnosis, they’ll take a sample of the affected tissue and send it to a laboratory for testing. A throat culture may also be taken if your doctor suspects diphtheria of the skin. How. is diphtheria treated?

Diphtheria is a serious condition, so your doctor will want to treat you quickly and aggressively. The first step of treatment is an antitoxin injection. This is used to counteract the toxin produced by the bacteria.

Make sure to tell your doctor if you suspect you might be allergic to the antitoxin. They may be able to give you small doses of the antitoxin and gradually build up to higher amounts. Your doctor will also prescribe antibiotics, such as erythromycin or penicillin, to help clear up the infection. During treatment, your doctor may have you stay in the hospital so you can avoid passing your infection on to others. They may also prescribe antibiotics for those close to you.

How. is diphtheria prevented? Diphtheria is preventable with the use of antibiotics and vaccines.

The vaccine for diphtheria is called DTa. P. It’s usually given in a single shot along with vaccines for pertussis and tetanus. The DTa. P vaccine is administered in a series of five shots. It’s given to children at the following ages: 2 months. In rare cases, a child might have an allergic reaction to the vaccine. This can result in seizures or hives, which will later go away.

Vaccines only last for 1. For adults, it’s recommended that you get a combined diphtheria- tetanus- pertussis booster shot once. Every 1. 0 years afterward, you’ll receive the tetanus- diphtheria (Td) vaccine. Taking these steps can help prevent you or your child from getting diphtheria in the future.
